For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0066] As Figures 1 to 11 shown, the present invention discloses an automatic traditional Chinese medicine decocting system.

[0067] The automatic traditional Chinese medicine decocting system includes a decocting pot, a dispensing and review unit 100, a decocting unit 200, a cleaning unit 300, and a conveying unit 400. The dispensing and review unit 100 is located upstream of the decocting unit 200, and the cleaning unit 300 is located downstream of the decocting unit 200. The conveying unit 400 is used to drive the decocting pot to flow between the dispensing and review unit 100, the decocting unit 200, and the cleaning unit 300.

[0068] In this embodiment, the dispensing and review unit 100 includes an automatic dispensing device 101 that can intelligently dispense traditional Chinese medicine materials according to a prescription, and a manual review device 102 that checks whether the dispensed traditional Chinese medicine materials are incorrect and makes corrections. The automatic dispensing device 101 is located upstream of the manual review device 102. The dispensing and review unit 100 is also equipped with a prescription binding and decoction piece dispensing system, which is signal-connected to the automatic dispensing device 101. By inputting prescription information into the prescription binding and decoction piece dispensing system, the prescription binding and decoction piece dispensing system sends the prescription information to the automatic dispensing device 101, and the automatic dispensing device 101 can dispense traditional Chinese medicine materials according to the prescription information.

[0069] After the automatic dispensing device 101 finishes dispensing traditional Chinese medicine materials, the dispensed traditional Chinese medicine materials are sent to the manual review device 102 for manual review. After passing the manual review, if the dispensed traditional Chinese medicine materials are correct, the dispensed traditional Chinese medicine materials are packed into a medicine bag and put into the interior of the decocting pot. If the dispensed traditional Chinese medicine materials are incorrect, re-dispensing is required, and the prescription binding and decoction piece dispensing system automatically cancels the prescription corresponding to the traditional Chinese medicine and prompts the personnel to re-enter the prescription.

[0070] In the present invention, the decocting pot includes an inner pot and an outer pot, and the inner pot can be sleeved inside the outer pot. A water leakage hole is opened on the bottom side wall of the inner pot for discharging the medicinal liquid from the inner pot. When decocting traditional Chinese medicine materials, the traditional Chinese medicine materials are put into the inner pot of the decocting pot.

[0071] The traditional Chinese medicine automatic decocting system is also equipped with a control circuit module. Sensors for obtaining status signals and sensors for executing commands are provided on all devices in the traditional Chinese medicine automatic decocting system, which are used to obtain the working status of each device and control each device to independently execute actions.

[0072] In this traditional Chinese medicine automatic decocting system, the decocting process of traditional Chinese medicine materials is realized by the continuous rotation of multiple individual decocting pots in the conveying unit 400. Each step of the traditional Chinese medicine decocting process is completed by a specific device processing the traditional Chinese medicine in the decocting pot at a specific device.

[0073] In the prescription of traditional Chinese medicine, different requirements for each step of the decocting process can also be recorded when decocting the traditional Chinese medicine pieces of the prescription. For example, the decocting duration, decocting temperature, etc. of the traditional Chinese medicine materials. The control circuit module adjusts the processing technology of the traditional Chinese medicine in the decocting pot by each device according to each input prescription information. For example, the residence time of the decocting pot at each device and the rotation sequence between each device, etc. In this way, it is possible to decoct traditional Chinese medicine decoctions of multiple prescriptions at the same time, and at the same time, the correct decocting process can be adjusted according to different prescriptions, and the working load of each device executing the decocting process can be controlled to ensure a high efficiency of the entire production line when decocting a large number of traditional Chinese medicine pieces.

[0074] The decocting unit 200 is used to heat the decocting pot filled with medicinal materials and water to complete the decocting process of the medicinal materials. The cleaning unit 300 is used to clean the decocting pot after the decocting is completed.

[0075] Refer to Figures 2 to 10 , Figures 2 to 10 shows the structure of the decocting unit 200 in detail.

[0076] The decocting unit 200 includes a vertically arranged rectangular frame 201. On one side wall of the frame 201, an upper truss 202 extending horizontally outward is provided at the top of the frame 201, and a lower truss 203 extending horizontally outward is provided at the bottom of the frame 201. The upper truss 202 and the lower truss 203 are arranged opposite to each other up and down. Both the upper truss 202 and the lower truss 203 are fixed on the frame 201, and the connection between the upper truss 202 and the lower truss 203 and the frame 201 can be fixed by bolts or welding.

[0077] A heating mechanism 204 is arranged between the upper truss 202 and the lower truss 203. The heating mechanism 204 is fixed on the frame 201, and the connection between the heating mechanism 204 and the frame 201 can be fixed by bolts or welding. There is a space between the heating mechanism 204 and the upper truss 202. There is also a space between the heating mechanism 204 and the lower truss 203.

[0078] The space left between the heating mechanism 204 and the upper truss 202 is used to place the decocting pot on the heating mechanism 204. When decocting medicine, place the decocting pot filled with medicine bags on the heating mechanism 204, and the heating mechanism 204 heats the decocting pot. The space left between the heating mechanism 204 and the lower truss 203 can accommodate the decocting pot. When the decocting pot is sent to the decocting device for heating and there is already a decocting pot on the heating mechanism 204 for decocting, the remaining decocting pots can be temporarily stored on the lower truss 203.

[0079] A conveyor line can also be installed in the space left between the heating mechanism 204 and the lower truss 203. The decocting pot is transported through the conveyor line. The non-decocted decocting pots can be sent to the decocting device for heating, and the decocted decocting pots can be sent to the next process through the conveyor line.

[0080] In this embodiment, a capping mechanism 205 is provided on the upper truss 202. When the decocting pot is placed on the heating mechanism 204, the capping mechanism 205 closes the feeding port of the decocting pot.

[0081] A control circuit module is also provided on the frame 201. The control circuit module is signal-connected to the capping mechanism 205 and the heating mechanism 204. The control circuit module is used to send control instructions to the capping mechanism 205 and the heating mechanism 204, and control the heating mechanism 204 and the capping mechanism 205 to perform corresponding actions according to the control instructions.

[0082] Specifically, the capping mechanism 205 includes a horizontally arranged fixing plate 2051, and the fixing plate 2051 is fixed on the lower surface of the upper truss 202. A pot lid 2052 is movably arranged below the fixing plate 2051. A first lifting component 2053 is arranged between the pot lid 2052 and the fixing plate 2051. The first lifting component 2053 is respectively connected to the fixing plate 2051 and the pot lid 2052, and the first lifting component 2053 is used to drive the pot lid 2052 to rise or fall.

[0083] The height points of the lifting of the pot lid 2052 include the highest point and the lowest point.

[0084] When the pot lid 2052 is at the highest point, the position of the pot lid 2052 is higher than the top of the decocting pot placed on the heating mechanism 204, so that the decocting pot can be placed on the heating mechanism 204 or removed from the heating mechanism 204.

[0085] When the pot lid 2052 is at the lowest point, the pot lid 2052 can press on the top end face of the decocting pot placed on the heating mechanism 204, thereby closing the top feeding port of the decocting pot.

[0086] A pressing plate 2054 is movably arranged directly below the pot lid 2052. The shape of the pressing plate 2054 in this embodiment is circular, and the pressing plate 2054 can extend into the internal support assembly 120 of the decocting pot to squeeze the medicine bag located on the bottom plate 124. A second lifting assembly 2055 is arranged between the pressing plate 2054 and the fixing plate 2051. The second lifting assembly 2055 is fixedly connected to the fixing plate 2051 and the pressing plate 2054 respectively. The second lifting assembly 2055 is fixed to the fixing plate 2051 and the pressing plate 2054 by bolts. The second lifting assembly 2055 is used to drive the pressing plate 2054 to rise or fall.

[0087] The height points at which the pressing plate 2054 rises and falls include a first height point, a second height point, and a third height point.

[0088] The first height point is the height point when the pressing plate 2054 is lifted to the highest position. When the pressing plate 2054 is at the first height point, the position of the pressing plate 2054 is higher than the top end of the decocting pot placed on the heating mechanism 204, so that the decocting pot can be placed on the heating mechanism 204 or removed from the heating mechanism 204. When the pressing plate 2054 is at the first height point, the height position of the pressing plate 2054 is lower than the height position of the pot lid 2052 at the highest point.

[0089] The second height point is the height point when the pressing plate 2054 is located at the top of the internal space of the decocting pot. When the pressing plate 2054 is at the second height point, the pressing plate 2054 is in a separated state from the medicinal materials placed in the decocting pot.

[0090] The third height point is the height point when the pressing plate 2054 is located at the bottom of the internal space of the decocting pot. When the pressing plate 2054 is at the third height point, the pressing plate 2054 is in a state of squeezing the medicinal materials inside the decocting pot.

[0091] During actual use, the number of times the pressure plate 2054 squeezes the medicine bag can be adjusted according to actual needs. In this embodiment, during the decoction of traditional Chinese medicine materials, the pressure plate 2054 squeezes the medicine bag in the decoction pot three times. When the decoction pot 100 is placed on the heating mechanism 204, the pressure plate 2054 is controlled to descend to the third height point to perform the first squeeze on the medicine bag in the decoction pot, and after the squeeze is completed, the pressure plate 2054 is controlled to rise to the second height point. When the traditional Chinese medicine materials in the decoction pot 100 are almost decocted, the pressure plate 2054 is controlled to descend to the third height point again to perform the second squeeze on the medicine bag, and after the squeeze is completed, the pressure plate 2054 is controlled to rise to the second height point. When the traditional Chinese medicine materials in the decoction pot 100 are completely decocted, the pressure plate 2054 is controlled to descend to the third height point again to perform the third squeeze on the medicine bag. After the squeeze is completed, the pressure plate 2054 is controlled to rise to the first height point, and the pot cover 2052 is lifted to the highest position, so that the pot cover 2052 opens the feeding port of the decoction pot, and the pressure plate 2054 is separated from the decoction pot.

[0092] In this embodiment, a plurality of guide rods 2056 are arranged between the pressure plate 2054 and the fixing plate 2051, and the number of the guide rods 2056 is multiple. In this embodiment, the number of the guide rods 2056 is four, and the four guide rods 2056 are arranged in a circumferential array with the central axis of the pot cover 2052 as the center line. One end of the guide rod 2056 is fixed to the pressure plate 2054, the other end of the guide rod 2056 extends above the fixing plate 2051, and the rod body of the guide rod 2056 sequentially penetrates through the pot cover 2052 and the fixing plate 2051. At a position on the fixing plate 2051 opposite to the guide rod 2056, a through hole for the guide rod 2056 to pass through is formed, and the aperture of the through hole is larger than the rod diameter of the guide rod 2056. The guide rod 2056 is slidably connected to the fixing plate 2051. Similarly, at a position on the pot cover 2052 opposite to the guide rod 2056, a through hole for the guide rod 2056 to pass through is formed, and the aperture of the through hole is larger than the rod diameter of the guide rod 2056, and the guide rod 2056 is slidably connected to the pot cover 2052.

[0093] On the lower surface of the fixing plate 2051, guide sleeves 20511 with the same number as the guide rods 2056 are fixed, and the guide sleeves 20511 and the guide rods 2056 are arranged in a one-to-one correspondence. The guide sleeves 20511 and the corresponding guide rods 2056 are coaxially arranged. The guide rods 2056 pass through the inner holes of the corresponding guide sleeves 20511. The guide rods 2056 and the guide sleeves 20511 are slidably connected to each other.

[0094] Preferably, a limiting ring 20561 is provided at one end of the guide rod 2056 extending above the fixed plate 2051, and the limiting ring 20561 is fixed to the guide rod 2056. The outer diameter of the limiting ring 20561 is greater than the aperture diameter of the perforation on the fixed plate 2051. When the pressure plate 2054 moves downward, the limiting ring 20561 can abut against the upper surface of the fixed plate 2051 to limit the moving stroke of the guide rod 2056 and prevent the separation between the guide rod 2056 and the fixed plate 2051.

[0095] Specifically, the first lifting assembly 2053 includes a vertically arranged air cylinder 20531, and the cylinder body of the air cylinder 20531 is fixedly connected to the fixed plate 2051. The piston rod of the air cylinder 20531 faces the direction where the pot lid 2052 is located. The piston rod of the air cylinder 20531 is relatively fixed to the pot lid 2052. When the piston rod of the air cylinder 20531 extends out of the cylinder body, the piston rod of the air cylinder 20531 pushes the pot lid 2052 to move the pot lid 2052 downward. When the piston rod of the air cylinder 20531 retracts into the cylinder body, the piston rod of the air cylinder 20531 pulls the pot lid 2052 to move the pot lid 2052 upward.

[0096] Specifically, the second lifting assembly 2055 includes a vertically arranged electric cylinder 20551, and the electric cylinder 20551 is located above the fixed plate 2051. An installation sleeve 20552 is arranged between the cylinder body of the electric cylinder 20551 and the fixed plate 2051, and the installation sleeve 20552 is vertically arranged. One end of the installation sleeve 20552 is fixed to the fixed plate 2051, and the other end of the installation sleeve 20552 is fixed to the cylinder body of the electric cylinder 20551. The push rod of the electric cylinder 20551 faces the inner hole of the installation sleeve 20552, and the push rod of the electric cylinder 20551 extends into the interior of the installation sleeve 20552.

[0097] A connecting rod 20553 is arranged in the inner hole of the installation sleeve 20552, and the connecting rod 20553 is coaxially arranged with the push rod of the electric cylinder 20551. One end of the connecting rod 20553 is butt - fixed to the push rod of the electric cylinder 20551, and the other end of the connecting rod 20553 sequentially passes through the fixed plate 2051 and the pot lid 2052 and is connected to the pressure plate 2054. The connecting rod 20553 and the pressure plate 2054 are fixed by bolts.

[0098] Preferably, the central axis of the connecting rod 20553 is coaxial with the central axis of the pressure plate 2054.

[0099] When the push rod of the electric cylinder 20551 extends out of the cylinder block, the push rod of the electric cylinder 20551 pushes the connecting rod 20553, and the connecting rod 20553 pushes the pressure plate 2054, causing the pressure plate 2054 to move downward. When the push rod of the electric cylinder 20551 retracts into the interior of the cylinder block, the push rod of the electric cylinder 20551 pulls the connecting rod 20553, and the connecting rod 20553 pulls the pressure plate 2054, causing the pressure plate 2054 to move upward.

[0100] By using the electric cylinder 20551, the output force of the electric cylinder 20551 can be controlled, thereby controlling the extrusion force of the pressure plate 2054 on the medicine package. When the medicine package is relatively large, the output force of the electric cylinder 20551 can be adjusted to increase the output force of the electric cylinder 20551, thereby ensuring the extrusion effect of the pressure plate 2054 on the medicine package.

[0101] A torque sensor is arranged inside the electric cylinder 20551. The torque sensor is installed in the driving part of the electric cylinder 20551, such as between the motor and the load of the electric cylinder 20551. The torque sensor is a device capable of measuring the rotational torque and is usually composed of an elastic element and a measuring element. When an external force acts on the elastic element, the elastic element will produce a tiny deformation. By measuring this deformation, the magnitude of the torque acting on the sensor can be calculated. When the electric cylinder 20551 controls the pressure plate 2054 to extrude the medicine package, the torque sensor can detect and feedback the torque value in real time to ensure the stable operation of the electric cylinder 20551 under various working conditions.

[0102] The torque value feedback by the torque sensor can obtain the extrusion force when the pressure plate 2054 extrudes the medicine package. According to the different sizes of the medicine packages and the quantity of medicinal materials contained in the medicine packages, the output force of the electric cylinder 20551 is adjusted, and the extrusion force of the pressure plate 2054 on the medicine package is adjusted by adjusting the magnitude of the output force of the electric cylinder 20551, so as to avoid excessive extrusion force applied by the pressure plate 2054 to the medicine package, thereby causing damage to the inner support assembly 120.

[0103] In this embodiment, a spray head 2057 is installed on the pot lid 2052. A water supply mechanism 206 connected to the spray head 2057 is installed on the frame 201. The water supply mechanism 206 can supply water to the interior of the spray head 2057. The water supplied into the interior of the spray head 2057 through the water supply mechanism 206 is sprayed into the decocting pot for decocting medicinal materials through the spray head 2057. The water outlet part of the spray head 2057 faces the pressure plate 2054, so that the water sprayed by the spray head 2057 can be sprayed onto the pressure plate 2054.

[0104] Similarly, the water supply mechanism 206 is signal-connected to the control circuit module. The control circuit module sends a control instruction to the water supply mechanism 206, and the water supply mechanism 206 performs corresponding actions according to the control instruction.

[0105] In this embodiment, the number of nozzles 2057 is two. In the actual production and processing process, the number of nozzles 2057 is not limited to two, and can be one, three or more. In this embodiment, taking the number of nozzles 2057 being two as an example, the two nozzles 2057 are arranged opposite to each other in a mirror image with the central axis of the pot lid 2052 as the center line. The water outlet part of the nozzle 2057 is located below the pot lid 2052, and the water inlet part of the nozzle 2057 is located above the pot lid 2052. The nozzle 2057 penetrates through the pot lid 2052 and is fixedly connected to the pot lid 2052.

[0106] A tee 2058 is fixedly installed on the upper surface of the pot lid 2052. One of the interfaces of the tee 2058 is used to connect to the water supply mechanism 206. Among the remaining two interfaces of the tee 2058, one interface is connected to one nozzle 2057 through a pipe fitting, and the other interface is also connected to the other nozzle 2057 through a pipe fitting.

[0107] Specifically, the water supply mechanism 206 is fixed on the frame 201. The water supply mechanism 206 includes a water outlet section 2061, a water inlet section 2062, and a water pump 2063. One end of the water outlet section 2061 is connected to the water outlet of the water pump 2063, and the other end of the water outlet section 2061 is connected to the nozzle 2057. One end of the water inlet section 2062 is connected to the water inlet of the water pump 2063, and the other end of the water inlet section 2062 is a free end. The free end of the water inlet section 2062 is used to connect to a water source. After connecting the water inlet section 2062 to the water source, the water pump 2063 can extract water from the water source and send the water into the water outlet section 2061. The water entering the water outlet section 2061 is sent into the nozzle 2057 along the water inlet section 2062, and the water entering the nozzle 2057 is sprayed out and sprinkled on the pressure plate 2054.

[0108] A flow meter 2064 is installed on the water inlet section 2062. The flow meter 2064 can measure the amount of water passing through the water inlet section 2062, so as to calculate the amount of water sent into the cooking pot.

[0109] The water inlet section 2062 is made of a rigid pipe fitting and is fixed on the frame 201. The water pump 2063 is also fixed on the frame 201. The water outlet section 2061 is made of a flexible hose. The length of the water outlet section 2061 can meet the requirement that during the up and down movement of the pot lid 2052, the water outlet section 2061 will not be separated from the nozzle 2057. When the pot lid 2052 moves up and down, the water outlet section 2061 can be bent and deformed along with the movement of the pot lid 2052.

[0110] A fixing block 20532 is also provided between the piston rod of the cylinder 20531 and the pot cover 2052, and the fixing block 20532 is fixedly connected to the piston rod of the cylinder 20531 and the pot cover 2052. A pipe through hole 20533 is processed on the fixing block 20532 to penetrate the fixing block 20532 transversely. When the water outlet section 2061 is connected to the nozzle 2057, the water outlet section 2061 is passed through the pipe through hole 20533 of the fixing block 20532, and the water outlet section 2061 can be restricted by the pipe through hole 20533. When water flows through the inside of the water outlet section 2061, the vibration of the water outlet section 2061 caused by the water flow is reduced, so that the water outlet section 2061 can be kept stable, and the separation of the water outlet section 2061 and the nozzle 2057 is reduced.

[0111] At the same time, when the cylinder 20531 pushes the pot cover 2052 to move up and down, the end of the water outlet section 2061 that is connected to the nozzle 2057 can move up and down synchronously with the pot cover 2052, avoiding the water outlet section 2061 from being pulled, thereby preventing the water outlet section 2061 from being separated from the nozzle 2057 due to the water outlet section 2061 being pulled.

[0112] Specifically, the heating mechanism 204 includes a housing 2041, which is fixed on the frame 201. The upper surface of the housing 2041 is a horizontal plane. An induction cooker 2042 is embedded inside the housing 2041, and the cooktop panel of the induction cooker 2042 is exposed from the upper surface of the housing 2041. The cover pressing mechanism 205 is located directly above the induction cooker 2042.

[0113] Specifically, the stovetop panel of the induction cooker 2042 is flush with or higher than the upper surface of the housing 2041. A plurality of positioning blocks 2043 are fixed on the upper surface of the housing 2041, and the positioning blocks 2043 surround the stovetop panel of the induction cooker 2042 on the inner side. When the frying pot is placed on the induction cooker 2042, the bottom of the frying pot abuts against the positioning blocks 2043. By providing a plurality of positioning blocks 2043, the position of the frying pot when placed on the induction cooker 2042 can be restricted, so that the frying pot can be placed at the same position every time when placed on the induction cooker 2042, ensuring that the relative position between the induction cooker 2042 and the frying pot is the best heating position.

[0114] In this embodiment, a temperature sensor 207 is installed on the pot cover 2052, and the temperature sensor 207 penetrates the pot cover 2052 and extends to the bottom of the pot cover 2052. When the pot cover 2052 is covered on the top of the frying pot, the temperature sensor 207 extends into the frying pot, and the temperature sensor 207 can measure the temperature in the frying pot. The temperature sensor 207 is connected to the upper computer by signal.

[0115] In this embodiment, a plurality of through holes 20541 are formed on the surface of the pressing plate 2054, and the through holes 20541 are evenly distributed on the surface of the pressing plate 2054. When the pressing plate 2054 is lifted or lowered under the drive of the second lifting assembly 2055, the pressing plate 2054 squeezes the medicine bag located in the decocting pot, and the medicinal liquid passes through the through holes 20541 on the pressing plate 2054. When the medicinal liquid passes through the through holes 20541, the flow rate of the medicinal liquid increases. Since the pressing plate 2054 lifts and stirs the medicinal liquid, the flow of the medicinal liquid can wash the medicine bag, so that the medicinal properties of the medicinal materials in the medicine bag can be better decocted, and the concentration of the decocted medicinal liquid is increased.

[0116] In this embodiment, the number of the induction cookers 2042 is two, and the two induction cookers 2042 are arranged side by side on the housing 2041. Correspondingly, the number of the pressing cover mechanisms 205 is also two, and one pressing cover mechanism 205 and one induction cooker 2042 form a group. The two induction cookers 2042 are arranged side by side. Similarly, the two pressing cover mechanisms 205 are also arranged side by side.

[0117] When decocting the medicinal materials, place the decocting pot filled with the medicine bag and water on the cooking surface of the induction cooker 2042, and start the induction cooker 2042 to heat the decocting pot. After the decocting pot is placed on the cooking surface of the induction cooker 2042, the first lifting assembly 2053 drives the pot cover 2052 to move downward, and the pot cover 2052 covers the top of the decocting pot to seal the feeding port of the decocting pot. The second lifting assembly 2055 drives the pressing plate 2054 to move towards the bottom of the decocting pot, so that the pressing plate 2054 can squeeze the medicine bag in the decocting pot. After the pressing plate 2054 squeezes the medicine bag, the second lifting assembly 2055 lifts the pressing plate 2054 to complete one squeezing of the medicine bag. During the process of decocting medicine, the second lifting assembly 2055 controls the pressing plate 2054 to lift and lower, so as to realize the squeezing of the medicine bag, make the medicine bag contact the medicinal liquid more fully, make the medicinal properties of the medicinal materials be decocted more fully, and improve the concentration of the decocted medicinal materials.

[0118] When the traditional Chinese medicine decoction in the decocting pot is finished decocting, and the concentration of the traditional Chinese medicine decoction exceeds the required concentration of the traditional Chinese medicine decoction, since the water supply mechanism 206 is arranged on the pot cover 2052, hot water can be replenished into the interior of the decocting pot through the water supply mechanism 206, so as to dilute the traditional Chinese medicine decoction in the decocting pot. When the decocting pot is short of water during the decocting process, the water supply mechanism 206 can also timely replenish water into the interior of the decocting pot.

[0119] When the water supply mechanism 206 replenishes hot water into the interior of the decocting pot, the hot water sent into the decocting pot by the water supply mechanism 206 flows through the pressing plate 2054, thereby flushing the pressing plate 2054 and washing the medicinal liquid adhering to the pressing plate 2054 into the decocting pot. While replenishing water into the decocting pot, the water supply mechanism 206 can play a role in cleaning the pressing plate 2054. Therefore, it is not necessary to disassemble and clean the pressing plate 2054, reducing the workload of cleaning the pressing plate 2054.

[0120] When using the decocting device disclosed in the present invention to decoct the medicinal materials in the decocting pot, the amount of water added into the decocting pot should be less than the set water addition amount, and the lacking amount of water is supplemented into the interior of the decocting pot through the water addition mechanism 206. When the water addition mechanism 206 replenishes water into the interior of the decocting pot, the water added by the water addition mechanism 206 simultaneously flushes the pressing plate 2054, flushing the medicinal liquid adhering to the pressing plate 2054 into the interior of the decocting pot, and saving the subsequent cleaning steps for the pressing plate 2054 at the same time.

[0121] The working process of the automatic Chinese medicine decocting system in the present invention for decocting Chinese medicine medicinal materials is as follows:

[0122] The dispensing and verification unit 100 first mixes the medicinal materials according to the prescription and checks whether the mixed medicinal materials are correct. If the mixed medicinal materials are correct, the mixed medicinal materials are added into the interior of the decocting pot. The decocting pot with the added medicinal materials is sent to the decocting unit 200 through the conveying unit 400.

[0123] When the decocting pot is sent to the decocting unit 200 through the conveying unit 400, the decocting pot is placed on the cooking surface of the induction cooker 2042 of the decocting unit 200 manually or by a handling device. When placing the decocting pot on the cooking surface of the induction cooker 2042.

[0124] After the decocting pot is placed on the cooking surface of the induction cooker 2042, the control circuit module sends a control instruction to the capping mechanism 205, controlling the first lifting assembly 2053 to push the pot lid 2052 downward until the pot lid 2052 covers the top feeding port of the decocting pot. When the pot lid 2052 covers the feeding port of the decocting pot, the pressing plate 2054 extends into the interior of the decocting pot through the feeding port of the decocting pot.

[0125] Start the water supply mechanism 206, and the water supply mechanism 206 sends water into the interior of the decocting pot until the amount of water sent into the decocting pot reaches the set value. Finally, start the induction cooker 2042 to heat the decocting pot, so that the induction cooker 2042 heats the decocting pot to decoct the medicinal materials in the decocting pot

[0126] During the decocting process of the medicinal materials in the decocting pot, the control circuit module controls the second lifting assembly 2055 to drive the pressing plate 2054 to move up and down. When the pressing plate 2054 completes one up-and-down movement step, it can squeeze the medicinal materials located inside the decocting pot once.

[0127] Set the number of times and the frequency of squeezing the medicinal materials by the pressing plate 2054 in the control circuit module. When the decocting pot decocts the medicinal materials, the second lifting assembly 2055 drives the pressing plate 2054 to squeeze the medicinal materials according to the parameters set in the control circuit module. The number of times and the frequency of squeezing the medicinal materials by the pressing plate 2054 are executed according to the parameters set in the control circuit module.

[0128] Specifically, in this embodiment, the pressing plate 2054 squeezes the medicine bag in the decocting pot at least three times, namely before the start of decocting, when the decocting is nearly finished, and after the decocting is completed. When the decocting pot 100 is placed on the heating mechanism 204, control the pressing plate 2054 to descend to the third height point to perform the first squeeze on the medicine bag in the decocting pot. After the squeeze is completed, control the pressing plate 2054 to rise to the second height point. When the medicinal materials in the decocting pot 100 are almost decocted, control the pressing plate 2054 to descend to the third height point again to perform the second squeeze on the medicine bag. After the squeeze is completed, control the pressing plate 2054 to rise to the second height point. When the medicinal materials in the decocting pot 100 are decocted, control the pressing plate 2054 to descend to the third height point again to perform the third squeeze on the medicine bag. After the squeeze is completed, control the pressing plate 2054 to rise to the first height point, and the pot cover 2052 rises to the highest position, so that the pot cover 2052 opens the feeding port of the decocting pot, and the pressing plate 2054 is separated from the decocting pot.

[0129] When the pressing plate 2054 squeezes the medicine bag in the decocting pot, the pressing plate 2054 can simultaneously drive the liquid medicine to roll inside the decocting pot. As the liquid medicine rolls inside the decocting pot, the liquid medicine can wash the medicinal materials, enabling the liquid medicine and the medicinal materials to come into fuller contact, so that the medicinal properties of the medicinal materials can be better decocted, and the concentration of the liquid medicine can be increased.

[0130] After the traditional Chinese medicine is decocted, take out the decocted liquid medicine and medicinal residues from the decocting pot, and package the decocted liquid medicine. After taking out the liquid medicine and medicinal residues from the decocting pot, the decocting pot is sent to the cleaning unit 300 through the conveying unit 400. The cleaning unit 300 performs a complete cleaning on the decocting pot, and finally the conveying unit 400 sends the cleaned decocting pot to the dispensing and review unit 100 for reuse.

[0131] The conveying unit 400 includes a plurality of conveying sections 401 at different heights, and a hoist 402 is provided between two adjacent conveying sections 401 at different heights. When the upstream conveying section 401 sends the decocting pot to the downstream conveying section 401, the decocting pot is first sent into the hoist 402 between the two conveying sections 401. The hoist 402 adjusts the height of the decocting pot to a height matching that of the downstream conveying section 401 and sends the decocting pot into the downstream conveying section 401.

[0132] The above are only the preferred embodiments of the present invention and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art of this patent, without departing from the scope of the technical solution of the present invention, can make some changes or modifications using the technical content prompted above into equivalent embodiments of equivalent changes.
